Give me a call tomorrow (25/10 around 10-11) and maybe we can set up a teamviewer session to see if I can help you.
Thanks for the help, I will call you
I'm sorry I could not find a solution. In fact I'm stumped and request the help of Todd or Wil or some other Adobe employee to help you out.
Why? The reason for requesting Adobe's help in this way is:
a. Chris has a limited knowledge of English and works with a Dutch version of Windows, which makes it difficult to communicate on the phone.
b. I have checked his system with Teamviewer and the system is more than adequate and is properly tuned/optimized for the task he wants to perform.
c. I can't find a solution to help him.
What is the problem?
System is an i7-2600K with 16 GB memory, P67 mobo, nVidia GTX 570 and 520 cards, 5 x 1 TB disks, 3 monitors, on-board audio.
Source material is simple DV PAL widescreen from a JVC camera. Sequence settings match, no problems here.
Playing a clip with WMP shows no problem, playing from the camera to a TV shows no problem, but playing from the timeline in a CS5.5.1 project results in a clearly audible rattling that is comparable to the rattling one has when projecting old 8 mm film, only louder. This was clearly audible for me over the phone.
I have no idea where to start looking for a solution, because his system looks good from all sides, is properly tuned, has more than enough horsepower to edit simple DV material.
So please Todd, Wil or anybody else from Adobe, can you help Chris?
Is it only those clips? Are there other types of media to try out?
I don't know what the problem could be, if you select a clip and use the clip pull down menu and choose audio> render and replace, it might help, and is a pretty quick work around. Also, you might try the fill left and fill right audio filters to see if you can isolate the problem to one channel or the other.
The could be a camera issue. I know that we had 3 perfectly good sony pdx-10 DVcam cameras at work that if the audio were recorded at 48Khz Stereo, premiere and some other NLEs would discard the right channel and have whatever was on the left channel show up as a mono clip.
You might try capturing the DV with a separate program.
It's only when I play the clips from PPRO 5.5. Even when I render a clip you can follow the rendering on the audiosignal like an old 8mm projector.Or when I transport the cursor along the track you can follow the te cursor on the audio signal, even when all the audio tracks are test to "out". It only happens when I play the timeline.
Playing the clips on other media as WMP this is not heard. When I play a totally other (not made by me) clip on WMP there also is no disturbing signal.
Playing the clip directly from tape also the signal is clean. When I play the clip directly from the projectscreen (where the imported projects are shown) the audio is clean.
It seems that only playing from the timeline causes probems.
Have you tried a new timeline?
I didn't see a clear answer to one of Jim's early questions:
Does this just happen with certain specific clips? Or does it happen with all clips?
It sounds like it's with all clips. My first suspicion is the onboard audio driver isn't very ASIO friendly. I'd try looking for an audio driver update, or try a different ASIO compatible audio driver (I forget which exactly, but I seem to remember elsewhere on this forum posts about people installing a substitute audio driver that worked fairly well).
Also, before going the route of an alternate driver, check the ASIO settings in the preferences - maybe changing the buffering length might have an impact.
Yes Jim, I tried a new timeline but the problem remains. We tried various different clips, all show the same behaviour.
Follow up: did a quick search - check out http://www.asio4all.com/ as a potential audio driver substitute. (Note, I haven't tried this personally, but quite a few people have successfully used this with PPro / Audition apparently.)
I will try to change the driver after I finished my project to avoid problems during the editing. Maybe it helps.
I hope to finish it next week and reports as soon as the results are ready.
Thanks for the help untill now.
